communicate. the fact that there are no distress calls tells me something happened a thousand feet below the aprove. >> when you say a thousand feet on approach, how long are we talking from 1,000 feet and putting wheels on the ground? >> oh, 35, 40 seconds. >> when you're coming in fast like that, it's a heavy plane certainly, the fact that that's on an auto pilot or auto landing or the pilot is doing it themselves, can the plane be automatically landed without pilot intervention? >> it can but in that particular runway, that particular approach, on a day like that without any weather out there, it probably would not have been auto landed. the auto throttles would have been controlling the speed but i would anticipate the pilots would have been commanding the flight path. >> okay. let's say the pilot realizes, uh-oh, we are too low.
